Another is that it supports Ada (32 bit x86 on linux only for the moment)
and Fortran to some extent.  I'm currently adding build instructions for
these two languages to http://llvm.org/docs/CFEBuildInstrs.html (should
be up in a day or two).  The release notes detail what works and what
doesn't.

Ciao,
